[Python] SSL: CERTIFICATE_VERIFY_FAILED when installing TensorFlow Object Detection API on...

I am trying to install the TensorFlow Object Detection API in a Python virtual environment on Windows 11, but I am getting repeated SSL errors.

The problem occurs when I run the python setup.py install command in the models/research folder. The output ends with the following errors:

Installed c:\users\user\projectefratsh\tf2.12_env\lib\site-packages\object_detection-0.1-py3.8.egg

More details: OS: Windows 11 Python version: 3.8 pip version: Updated TensorFlow version: 2.10 GPU GPU: : NVIDIA RTX 4050 (supported by TensorFlow GPU)

Object Detection API: Downloaded from GitHub: https://github.com/tensorflow/models/tree/master/research/object_detection NetFri: I use NetFri web filtering, and it may be causing the problem.

How can I resolve the SSL error and get pip to validate the pypi.org SSL certificates? Is it necessary to install specific CA certificates for NetFry? Is there an alternative solution to installing the TensorFlow Object Detection API in this situation? Is there a way to check which sites NetFry is blocking? I'm looking for a permanent solution to the SSL issue, not just a temporary one. Thanks in advance for your help!
